Why are my gums so red
Red gums commonly reflect inflammation from plaque, irritation, infection, or a medical factor that needs examination.
The short answer
Red gums are usually inflamed because plaque irritates the gingival margin, although trauma, infection, mouth breathing, medicines, or other conditions can also contribute.
How should healthy gums normally look and feel?
Healthy gingiva is generally firm and closely adapted around the teeth. Inflammation increases blood flow and changes the tissue, so the gum edge may look red, swollen, tender, or prone to bleeding during brushing.
How can I clean very red gums safely?
Brush gently twice daily with a soft brush and clean between the teeth with floss or interdental brushes. Do not stop cleaning because of light bleeding, but arrange a dental cleaning and examination if the redness persists.
When should persistent red gums be checked?
Book care for persistent redness, frequent bleeding, bad breath, gum recession, loose teeth, or a localized swelling. Urgent assessment is needed for facial swelling, fever, severe pain, or trouble swallowing or breathing.
What could be causing my gums to look red?
Ask whether plaque, calculus, decay, trauma, or a medication could explain the appearance. Ask how deep the gum pockets are and whether professional debridement, a filling, or treatment for periodontal disease is needed.
Frequently asked questions
Can red gums heal?
Gingivitis caused by plaque can improve when plaque is removed consistently and a dentist treats any calculus or local irritant.
Why is one area red?
A single red area can be irritated by trapped food, a sharp filling edge, trauma, an ulcer, or a localized dental infection.
